Scott Armstrong has written an enthusastic review of Paul Goodwin's forthcoming book, Forewarned: A sceptic's guide to prediction. The book will be available in June. Scott's review follows...

Scott Armstrong and Kesten Green's "Forecasting methods and principles: evidence-based checklists" was published online on March 14.

The objective of the paper is "to help practitioners, academics, and decision makers use experimental research findings to substantially reduce forecast errors for all types of forecasting problems." The objective was met by providing four evidence-based checklists for designing and auditing forecasting procedures. 

Kesten Green's analysis of the outcome of a 10 year "bet" between Scott Armstrong's scientific forecast of global mean temperatures and warnings of a tipping point by former US vice president Al Gore has been posted to and various blogs. It is repeated here for the interest of the forecasting community. 

In the early 1980s, two of the authors of Principles of Business Forecasting, Robert Fildes and Keith Ord, were leaders in the movement to use experiments to determine which principles led to more accurate forecasts. The experiments show that forecasting methods today are capable of providing much more accurate forecasts that they were 50 years ago. This movement was a golden age for progress in forecasting. However, this knowledge has been not been widely adopted in business and government.

Scott Armstrong and Kesten Green are making a last call for help with their paper, "Forecasting methods and principles: Evidence-based checklists". They are ambitious for the paper: by the use of checklists, it is intended to make scientific forecasting accessible to all researchers, practitioners, clients, and other stakeholders who care about forecast accuracy.

Here is the abstract of the paper:
